Chapter 5—System Configuration and OperationPower Xpert C445 Global Motor Management Relay MN042003EN—January 2019 www.eaton.com 101Figure 102. 120 Vac Inputs and 120/230 Vac Outputs/C445 PowerNotes:1. The inputs on the Base Control Module are only used bythis Operation Mode if Fieldwire is selected for one ofthe control sources. If Fieldwire is not the Local orRemote control source, all 4 inputs may be used asgeneral purpose inputs or can be selected as thefeedback source for the CB aux contacts.2. Output 3 may be used as general purpose output for thisOperation Mode.3. If Fieldwire is the Local control source, Input 3 is theRemote input. When power is applied to Input 3, theC445 will be in Remote mode.4. If fieldwire is the Remote control source and 2-wirecontrol (default) is selected, Inputs 2 and 3 are unusedby this operation mode. They can be used as generalpurpose or selected as the feedback source for the CBaux contacts.5. Fusing: Although C445 product listings do not requirefusing on the high impedance line voltage measurementinputs, it may be necessary to provide overcurrentprotection of the supply leads in accordance withapplicable final installation specific local, state andnational electrical codes.6. C445UC... control user interfaces offer 4 additional24 Vdc digital inputs for general purpose use. Inputs 2and 3 can optionally be used as the feedback source forthe CB aux contacts.CLOSEI1 I2CH1CH2I3 I4 Q1 Q1 Q2 Q2 Q3 C Q3C D0 D1Optional ModbusCB MOTOROPERATOR24V CONOFFCH1CH2(+) Us(-) Us24 VDC(+) Us(-) Us120/240VACPE N LFB1FERRITEIC IC ICRESETREMOTEC445BA-SA...C445U…
